Apple TV App goes Black
While I am watching some series from the Apple TV app on my iMac (Retina 4K, 21.5-inch, 2019) the screen goes black, however, there is still dialogue sound. The iMac didn't go to sleep, only the Apple TV app window is black. I have turned the iMac on and off, including wiped the entire system and reinstalled everything, but no solution. Does anyone have a solution to this? Thanks in advance.
iMac 21.5″, macOS 13.1
